'7 Claims.

This invention relates generally to a machine for washing and scrubbing sand, gravel, stone and like materials, and more particularly to means for simultaneously effectingthe grading 5 and separating of the scrubbed and washed material. 7

One of its objects is the provision of a machine of this character for not onlylthoroughly and expeditiously washing and scrubbing the material by imparting thereto a positive tumbling or cascading and volcanoing-like motion, but at the same time providing simple means for effectually grading or screening the cleaned material by the gyratory motion imparted to the machine-body for producing the tumbling-like motion to the materialbeing cleaned.

Another object of the invention is to provide a simpleand inexpensive arrangement of scrubbing and screening means.

Other features of the invention reside in the construction and arrangement of parts herein after described and particularly pointed out in the appended claims.

In the accompanying drawings:-

Figure 1 is a central longitudinal section of a scrubbing machine embodying my improvements. Figure 2 is a cross section thereof taken substantially in the plane of line 2-2, Figure 1. Figure 3 isa view similar to Figure 2 showing a 30 different arrangement of grading decks. Figure .4 is a view similar to Figure 2 showing a modified arrangement of grading decks. Figure 5 is a view similar to Figure 1 showing a still further modification of the grading decks.

Similar characters of reference indicate corresponding parts throughout the several views.

1 In connection with the invention, a vibratory or shaking body is provided which may be of any suitable construction, that shown in the drawings, by way of example, being adapted to gyrate in a vertical plane and consisting of end Walls or plates l0, In between which are arranged one or more substantially trough-shaped scrubbing decks II for the material to be washed or scrubbed. This gyrating bodyis disposed in a substantially horizontal-position between suitable beams l2 and is balancedor. supported for rotating vibratory movement on a rotary shaft l3 journaled in suitable bearings 14 applied to the beams I2. This shaft constitutes the drive element of the machine and imparts to the body a positive gyratory movement, and to this end the shaft has eccentric portions l5adjacent its ends journaled in roller or like bearings [6 attached to the at W ls 0;? t e r t n b y.-

For the purpose of maintaining the machine in proper balance, the shaft I3 is provided with counter balanced wheels I 1.

While any number of scrubbing decks H may be employed, I have, by Way of example, shown 5 two which are disposed side by side in parallel relation, the material to be scrubbed, cleaned and washed being delivered thereto by any suitable means at one end thereof, and being discharged therefrom after the scrubbing and lo washing action through a discharge passage l8 disposed in the opposite end of each scrubbing deck. As shown in Figure 2, each scrubbing deck has an inner section or shell l9 spaced from the surrounding walls thereof, which provides a 15 roughened surface for imparting to the material a tumbling-like action in response to the gyrating motion of the screen body. During the scrubbing action water is sprayed over. the decks inany appropriate manner and the wash water 20 and the foreign or removed material passes 1 through the screen section [9 'into the bottom of the trough, from which it is discharged through openings 20 arranged in the bottom side of the scrubbing deck.

Arranged within each scrubbing deck II are a plurality of control bafiies or partitions 2|, 22 which are disposed in spaced relation lengthwise of the deck and are arranged to direct and guide the material in a substantially spiral-like course 30 through the scrubbing decks in response to the gyrating motion of the machine body. This action serves to break up and dislodge any foreign matter from the material being scrubbed. In

connection with these control bailies, which 35 are preferably disposed below the shaft l3 with the uppermost screen deck in communicating relation with the discharge passage I8 of each scrubbing deck H, the scrubbed material drop- 50 Ding by gravity onto one end of said uppermost screen deck. In the arrangement of the screens shown in Figures 1 and 2, they are inclined in the direction of length of the body l0 and are of different mesh so that in response to the gyrating acti on of the machine body, the washed madirection transversely thereof.

drained through the openings 26 'in'the bottom" of the scrubbing deck II from contacting with the cleaned material after its discharge through the openings l8 onto the uppermost screen deck 23, I provide deflecting walls 21 which slope downwardly from a point below the openings 7 20 to a point substantially centrally of the chine, in the manner shown in Figure 2. this rneans the water is directed to a point substantially centrally of the machine and thereupon drains through the respective screen-decks 23 without contacting with the cleaned material. In thearrangement shown in Figure 3, the screen decks 28 are disposed insets or groups, one group being disposed beneath each scrubbing deck below its discharge passage I8 and inclined toward the center of the machine in a Each group of screening decks terminates at its inner edges atv a point in spaced relation to the opposing edges of the companion group of screening decksjwhereby a space is provided for the discharge of the screened material.

In the embodiment of the invention shown in Figure fl,- a plurality of transversely inclined screening decks 29 are provided which likewise serve to screen and grade the cleaned material as it is discharged from the scrubbing decks.

In this .arrangement, .a deflecting wall 30 may be provided between the bottom of the scrubbing deck and the uppermost screening deck for directing the wash water discharged from the scrubbing deck to a point centrally of the. screen decks 29.

In Figure 5 is shown a still further arrangement of grading decks consisting of an upper deck 3i disposed lengthwise beneath the scrubbing decks II and extending from end to end thereof, and lower grading decks 32 disposed beneath the scrubbed material discharge l8 and terminating substantially centrally of the machine-body. A baffle or deflecting wall 33 is disposed between the scrubbing deck H and grading deck 3| for diverting the wash water to that part of the latter beyond the inner edges of the lower grading decks 32, whereby the wash wa- I ter and foreign matter contained therein will not come in contact with the already cleaned material while it is undergoing grading through the decks 31, 32. a

1. A machine for washing and scrubbing gravel and the like, comprising a gyrating body including a substantially trough-shaped scrubbing deck for the material to be treated disposed at one side of its gyrating axis, said deck extending generally, in the direction of the bodyaxis and having openings in its bottom for the discharge of wash-water and foreign matter and a discharge at one end for the washed and, scrubbed material, and grading decks for such material mounted on said gyrating body and disposed at the opposite side of its gyrating axis below the scrubbing deck.

2. A machine for washing and scrubbing gravel and the like, comprising a gyrating body including a substantially trough-shaped scrubbing deck for the material to be treated, said deck extending generally in the direction of the body-axis at one side thereof and having openings'in'its bottom for the discharge of washwater and foreign matter and a discharge at one end for the washed and scrubbed material, means in said deck for baffling the fiow of material therethrough and causing it to take a spiral, tumbling-like'course from the feed end toward the discharge end of the deck, and screening decks mounted on said gyrating body at'the oppositesideof its gyrating axis and below the scrubbing deck for receiving the scrubbed material and grading the same.
